A foreground-marginalized 'BK-lite' likelihood for the tensor-to-scalar ratio
Heather Prince, Erminia Calabrese, Jo Dunkley
The current limit on the tensor-to-scalar ratio from the BICEP/Keck Collaboration (with r<0.036 at 95% confidence) puts pressure on early universe models, with less than 10% of the…

A cross-bispectrum estimator for CMB-HI intensity mapping correlations
Kavilan Moodley, Warren Naidoo, Heather Prince +1
Intensity mapping of 21cm emission from neutral hydrogen promises to be a powerful probe of large-scale structure in the post-reionisation epoch. However, HI intensity mapping (IM)…

The Atacama Cosmology Telescope: High-resolution component-separated maps across one-third of the sky
William R. Coulton, Mathew S. Madhavacheril, Adriaan J. Duivenvoorden +151
Observations of the millimeter sky contain valuable information on a number of signals, including the blackbody cosmic microwave background (CMB), Galactic emissions, and the Compt…
